Question

我已经按照以下说明成功安装了Yara：https://yara.readthedocs.io/en/v3.8.1/gettingstarted.html#compiling-and-installing-yara，包括执行./configure --with-crypto，并且没有看到任何错误消息。

进入“进行检查”步骤时，出现以下两个失败。

PASS: test-alignment

PASS: test-api
FAIL: test-rules
FAIL: test-pe
PASS: test-elf
PASS: test-version

打开SSL版本：OpenSSL 1.0.2k-fips 26 Jan 2017

如果我运行phpmalwarefinder，我会得到

我在这里发布了说明 https://github.com/nbs-system/php-malware-finder/issues/94

这是我如何运行它，还有一个小补丁

git clone git@github.com:VirusTotal/yara.git
cd yara/
sudo yum install autoconf automake libtool  openssl-devel.x86_64  flex bison
YACC=bison ./configure
make

设置查找器

cd ..
git clone git@github.com:nbs-system/php-malware-finder.git
cd php-malware-finder/
~/GitHub/devops/yara/yara  -r ./php-malware-finder/php.yar  ~/GitHub/sourcetoscan/

必须对此进行修补（无重复）

diff --git a/php-malware-finder/php.yar b/php-malware-finder/php.yar
